• Time required: three to six 50 minute class periods

What are molecules of life? Science has proven that atoms unite into molecules, and that when molecules exchange atoms, new substances are created. Inorganic substances such as water, carbon dioxide, and oxygen, together with organic substances such as carbohydrates, lipids, and proteins, make the protoplasm found within the cells of living organisms. The molecules of life are the molecules that make protoplasm. In the Complete Molecules of Life kit, students study the chemistry of carbohydrates, fats, and proteins. Durable, color-coded plastic atoms are assembled, disassembled, and reassembled quickly and easily into 3-D molecules that provide highly graphic and extremely motivating learning experiences.

Carbohydrates, lipids, and proteins can be completed as a series of lab activities or as separate units. Students can also work independently for enrichment or remedial study. Each module can be systematically subdivided into smaller sections, so students can do the work when most appropriate.
